I don't come from a gun family, so I don't really know what is considered good accuracy with a pellet gun. I just went out and shot 5 pellets from a Crossman Pumpmaster from Walmart at 30 yards and had one bulls eye and kept everything in a 2 inch group. Then I backed out to 40 yards and shot 4 times and the group expanded to 2.5 inches (Including the original group) and I took one shot at 50 yards and was way off... I hit low on the target way off to the right. (I was having trouble standing still on an angle because of a hill) Is this pretty average?
